Design Of Control System Of Potato Sorter Based On Machine Vision

Potato is one of the main crops in Ningxia region. For a long time, the potato grading work commonly used artificial way, but grading potatoes directly affects their market competitiveness and economic efficiency. In this paper, according to the low automation level in the potato grading industry, based on the current research results of domestic and foreign various kinds of agricultural products to design a control system of the potato based on machine vision. The main subjects and conclusions of the research are as follow:(1)Proposed the integrated design of potato grader based on machine vision. The control system ofPotato grader is composed of five parts, including potato climbing roller conveyor、 potato soft brush conveyor、potato collection conveyor、optical instrument supporting conveyor and potato grading conveyor.(2)Accodding to the workflow of the potato sorter,design the control system of the potato climbing roller conveyor、potato soft brush conveyor、potato collection conveyor、optical instrument supporting conveyor and potato grading conveyor. Present the control strategy and design the hardware and software of the control system.(3)Using the Matlab software to simulate the method of potato counting based on image processing. Using Proteus software to simulate the control system of potato grading and carrying out the hierarchical control system. Verifying the feasibility of the design by simulating.In this paper, the design of the control system of the potato grader based on the machine vision provided technical support of the control for the potato sorter and ensure the sorter can also achieve accurate、rapid and nondestructive effect for the automatic grading.
